I am doing intermediate Cypher Queries course. I started getting this error after completing about 8% course. Bolt Connection Error -No connection found, did you connect to Neo4j? How to resolve this issue? Thanks in advance for your help.
After trying for some time, I got a Connect to Neo4j window in which I entered the credentials for the connection (Authentication type Username/Password). Now I get the following error - "Server is taking long time to respond. ServiceUnavailable: Failed to establish connection in 30000ms"
It's possible that there is expired connection data in your cookies for your browser. Can you try clearing cookies and refreshing the GraphAcademy page?
I cleared cookies and refreshed the GraphAcademy page. Get this error ServiceUnavailable: Failed to establish connection in 30000ms while connecting to the sandbox
From where are you connecting? Does the sandbox exist? If you are using the embedded sandbox for the course (which uses the Recommendations sandbox), it will automatically recreate the sandbox if it does not exist. It may take a few minutes before you see the $neo4j prompt. There is not VPN or ad blocker interfering is there?
There is no VPN or ad blocker. The sandbox was working fine till day before yesterday. There was a notification for termination of the sandbox yesterday. Subsequently when I logged in to the course, a new sandbox was created. And I worked a bit on the course last night. So yes, the sandbox exists. It is still shown. It is the Recommendations sandbox - the embedded sandbox from the course. But today it is not working.
